Answer:
m = 25.98 g
Explanation:
Given data:
Density of copper metal = 8.96 g/mL
Volume of copper metal block = 2.90 mL
Mass of copper metal block = ?
Solution:
The volume of given block of copper is equal to the volume change of water by adding this block.
Density formula:
d = m/v
by putting values,
8.96 g/mL = m/ 2.90 mL
m = 8.96 g/mL × 2.90 mL
m = 25.98 g
Answer: 64
Explanation:
you just multiple the 3 numbers to get the answer (i’m in chemistry and just did this question lol)
1.7960L
Explanation:
the mass of the gas is constant in both instances
pv/T=constant(according to pv=nRT)
745mmHg*2L/298K=760mmHg*v/273K
v=1.7960L
