1 is ok.
2 is ok but if your prof is picky about the number of significant figures you may want to adjust this.
3. Is that 35.0 GRAMS. If so I get the 2.15 but I don't agree with the exponent.
4 same comment about s.f.
5 I used 74 x 5.6 and didn't get 318
6. I used 24.3 and didn't get that. You must have used 24.
Remember that with problems like this answers can't agree unless both of us use the same set of numbers. It's always good when doing problems like this to show what numbers you used.
Please check each of these mole statements. Correct me if I'm wrong!
1. 59g of hydrochloric acid (HCL)=____moles
I got 1.6 moles
2. 4.6 moles of sodium hydroxide (NaOH)=___ grams
I got 184 grams
3. 35.0 of sulfuric acid (H2SO4)=__ f.u sulfuric acid
I got 2.15x10^25th power molecules
4. 3.4x10^24th power formula units of sodium chloride=____g
I got 330 g
5. 5.6 moles of calcium hydroxide=____g
I got 319 g
6. 1 magnesium atom=_____g
I got 3.986x10^-23rd power
