Solve without using a calculator. on a cold day near the ocean, it was found that 8 g of an unknown gas occupies a volume that i
s a little less than 6 l. based on this information, what is the most likely identity of the unknown gas?
1 answer:
Assuming that the gas acts like an ideal gas so that the
molar volume is Vm = 22.4 L / moles, we can calculate for the number of moles.
number of moles = 6 L / (22.4 L / mol) = 0.2679 moles
So the molar mass of this gas is:
molar mass = 8 g / 0.2679 moles = 29.9 g/mol
The value is around 32 g/mol which is the molar mass of
oxygen. Therefore the answer is:

I believe that answer is nitrogen.
Mass of 1 staple = 6.8 g/210 staples
mass of 1 staple = 0.032380952 g
Hope that helps!!
Explanation:
M.A = load / Effort
efficiency = M.A/V.R X 100
75 = M.A / 4 X 100
75 = 25 X M.A
M.A = 75/25 = 3
M.A = load / effort
3 = 100/E
E = 100/3 = 33.333

Just divide 12 by 3, so if it takes 3 seconds, then every second, it goes up 4.
