Question

Sodium has a density of 1.95 g/mL If the volume of some sodium is 9.0 L what is the mass

Answer 1

17550g

Step-by-step explanation:

You want to use the equation D=M/V. You are given density in g/mL, so you just need to multiply that by 9L, but first you want the mL and L to match, so you change the 9L to 9000mL (knowing there is 1000mL in 1L). Then solve algebraically by multiplying the 9000mL and the 1.95g/ml, making the mL cancel, leaving you with your answer in grams.

Hope this helps!
