The density of aluminum is 2.70 g/mL. What is the mass of a 15.9 cm X 11.6 cm X 7.3 cm block of aluminum?
Hi, the answer is 3510g
Step-by-step explanation:-
We know that density of a substance tells us the mass of exactly one unit of volume of given substance. In this question,
Aluminium density = 2.70g/mL
So,
V = L x W x H = 1300 cm³ = 1300 mL
m = D x V = (2.70 / 1300) = 3510g
