Question

What is the mass, with correct number of significant figures, of a sample of silver that has a density of 10.5 grams/mL and a

volume of 5.2 mL?
0 55 g
0 54.6 g
O 0.495 g
0 0.5 g

Answer 1

Step-by-step explanation:

V = 5.2 mL This has 2 sig digs, so the answer must have 2 sig digs.

d = 10.5 grams / mL

m = density * volume

mass = 10.5 * 5.2

mass = 54.6 grams but you need to consider the sig digits

mass = 55 grams.
