Answer: The mass of the sample is 1264.800 kg.
Explanation:
Mass of the piece of copper = m
Volume of the copper price =
m = 1,264,800 g = 1,264.800 kg (1 kg = 1000 g)
The mass of the sample is 1264.800 kg.
Answer:
14g
Explanation:
assuming that N2 is a gas, use the gas formula ( mole = volume/24) to find the number of moles
then once you have found the moles (0.5 mol) use the (mole = mass/mr) formula to find the mass
so, 0.5 x 28 = 14g
