Object a has a mass of 12 G and a volume of 8 cm3 object be has a mass of 20 G and a volume of 8 cm3 which object has a greater
solniwko [45]

Answer:

Option C = object B by 1 gram per cubic cm.

Explanation:

Given data:

Mass of object A = 12 g

Volume of object A = 8 cm³

Mass of object B = 20 g

Volume of object B = 8 cm³

Densities = ?

Solution:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Density of object A:

d = m/v

d = 12 g/ 8 cm³

d = 1.5 g/cm³

Density of object B:

d = m/v

d = 20 g/ 8 cm³

d = 2.5 g/cm³

object b has high density.

A laboratory technician needs to prepare 500 milliliters of a 2 M solution of sodium hydroxide (NaOH) in a flask. The flask has
Marat540 [252]

Answer:

40 g NaOH

Step-by-step explanation:x

To make 500 mL of a 2 mol·L⁻¹ solution, the technician must measure the correct mass of NaOH.

Step 1. Calculate the <em>moles of NaOH </em>

c = n/V     Multiply both sides by V

n = Vc

c = 2 mol·L⁻¹

V =0.5 L

n = 0.5 × 2

n = 1 mol NaOH

Step 2. Calculate the <em>mass of NaOH </em>

The molar mass of NaOH is 40.00 g/mol.

m = 1 × 40.00/1

m = <em>40 g NaOH </em>

The technician must measure <em>40 g of NaOH</em>.
