Explanation:
grams/MM=ans./volume(L) = M
4/58.45=ans./3.8=.018 M
I think the first blank is "solidity" and second is "object."
First convert 0.163 grams of N2O to mol by dividing it with
the molecular weight. The molecular weight of N2O is 44 grams/mol. The answer
would be 3,79x10^-3. Then multiply it with 2 since there are 2 Nitrogen in one
mole of N2O. Therefore, there are 7.41x10^-3 moles of Nitrogen.
