Answer:

d = 14.9 g/mL

Explanation:

Given data:

Mass of metal = 22.4 g

Volume of eater = 3.2 mL

Volume of water + metal = 4.7 mL

Density of metal = ?

Solution:

Volume of metal:

Volume of metal = volume of water+ metal - volume of water

Volume of metal = 4.7 mL - 3.2 mL

Volume of metal = 1.5 mL

Density of metal:

d = m/v

d = 22.4 g/ 1.5 mL

d = 14.9 g/mL

Calculate the mass of 29.8 mL of aluminum, which has a density of 2.00 g/mL.
MaRussiya [10]

Answer:

The answer is

<h2>59.6 g </h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

Density of aluminum = 2.00 g/mL

volume = 29.8 mL

The mass is

mass = 2 × 29.8

We have the final answer as

<h3>59.6 g</h3>

Hope this helps you

The buildup of sediment where a river empties into a slow-moving or nonmoving body of water is known as a/an
777dan777 [17]

The buildup of sediment in which a river empties right into a slow-transferring or non transferring frame of water is referred to as a Delta.

<h3>What is Delta ?</h3>

Deltas are wetlands that shape as rivers empty their water and sediment into some other frame of water, together with an ocean, lake, or some other river.

A form of soil made nearly completely of windblown sediment is referred to as Loess.

The natural count number in soil comes from decaying flora and animals and their waste products.

Clay, that's made of tiny debris and drains water very poorly, is one of the essential additives of soil.

A form of soil referred to as peat is maximum probably to shape in a/an Coastal surroundings in Tropical placing.

Water enables withinside the improvement of soil with the aid of using carrying Mineral and vitamins from higher layers to decrease layers.

The Richness of nutrients from soil is not unusualplace in moist environments, like rain forests.

Quartz-wealthy determine cloth results in the improvement of Sandy soils.

The layers of soil composed specifically of natural count number are referred to as the O and A horizon.

A layer of soil wherein clay, iron, and different factors from the overlying soil accumulates is referred to as the B horizon, or subsoil.

  • Delta is stated to be a frame of sediments deposited whilst a river flows into a status water, together with the ocean or a lake.

  • Loess are wind blown deposits of silts and clay composed of quartz, feldspar and different minerals . Loess dominantly have excessive porosity.

  • Organic subjects compose specifically of stays of animal and flora . After this flora and animals dies they shape natural count number that provides to soil vitamins.

  • Clayey soil represent very tiny debris which have a bad draining cappotential because of it tiny bad spaces .

  • Tropical placing in a coastal surroundings affords the important environments for soils like peat to shape . It has plentiful of plant stays . Moreover peat is the primary degree of coal formation, containing wet and unconsolidated plant substances.

  • Minerals part of what help withinside the improvement of the soil .And additionally it is carried right all the way down to the earth with the aid of using water thru a procedure referred to as Leaching.

  • Richness of nutrient are not unusualplace in tropical surroundings which are moist and help plentiful life.

  • Sandy soil are fashioned from dad and mom substances containing minerals together with feldspar and quartz.

  • Horizon O and A are referred to as topsoil and are specifically compose of animal and flora stays and big quantity of minerals.

  • The subsoil or B Horizons consists of mineral together with irons , clay minerals because of percolation from the pinnacle soils and it has a tendency to build up here(subsoil).
