Answer:
ρ = 1.08 g/cm³
Explanation:
Step 1: Given data
Mass of the substance (m): 21.112 g
Volume of the substance (V): 19.5 cm³
Step 2: Calculate the density of the substance
The density (ρ) of a substance is equal to its mass divided by its volume.
ρ = m / V
ρ = 21.112 g / 19.5 cm³
ρ = 1.08 g/cm³
The density of the substance is 1.08 g/cm³.

<h3><u><em>
Option D: Evapotranspiration </em></u></h3>
<u><em>Water is removed both from the plants and the soil. Evapotranspiration is a process by which the water is removed from plants and ground and is added back into the atmosphere. From ground, water is removed in the form of evaporation from the soil. And from plants the water is removed by transpiration. Hence the term Evapotranspiration.</em></u>
Answer:
116.6 lbs
Explanation:
There are 2.2 lbs per Kilogram of weight - and likewise 0.454 Kilograms per pound - but instead of dividing by .454 I multiplied the weight by 2.2 to get 116.6 pounds (of course you could round up and get 117 but 116.6 is a little more accurate).
Answer:
The answer is
<h2>2.63 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
volume of silver = 0.25 cm³
density = 10.5 g/cm³
The mass is
mass = 10.5 × 0.25 = 2.625
We have the final answer as
<h3>2.63 g</h3>
