Q
Mole stands for ?
A
Molecular Weight (MW)
2
Q
Moles and grams are related based on the ?
A
Molecular Weight of a compound
3
Q
The number of grams in a substance will always be greater than the number of ?
A
Moles
4
Q
To go from Moles to grams you ? by the ?
A
Multiply
Molecular Weight
5
Q
To go from Grams to Moles you ? by the ?
A
Divide
Molecular Weight

Q
What is the MW (Moles)
10grams of Ca₃(PO₄)₂
A
First find the MW (previous module)
MW = 310.18
We are given the grams and need Moles
Larger (grams) to smaller (moles) we divide 10g / 310.18 = 0.03224 moles
7
Q
What is the Grams of
0.152 moles of Na₂SO₄
A
First find the MW (previous module)
MW = 142
Going from smaller (Moles) to larger (Grams) so we multiply 0.152 * 142 = 21.584g
CHM 095
