A liquid has a density of 16 g/mL. If you have 0.21 mL of liquid, what what is mass be

Explanation:

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

From the question

volume of liquid = 0.21 mL

density = 16 g/mL

The mass of the liquid is

mass = 0.21 × 16

We have the final answer as

Hope this helps you

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
