## melissa2 one year ago How many grams of NaOH are required to make 0.10 moles of NaOH? @Abhisar

1. Abhisar

Tell em molecular mass of Na , O and H

2. Abhisar

*me

3. Abhisar

Na =23, O=16 & H=1

4. Abhisar

Molar mass of NaOH= 23+16+1=40

5. melissa2

22.989769280 ± 0.000000020 g/mol Na

6. melissa2

H 1.007940 ± 0.000070 g/mol

7. Abhisar

40 grams of NaOH is required for making 1 mole, so for 0.10 moles 40*0.10=0.4 grams of NaOH is required.

8. melissa2

O 15.99940 ± 0.00030 g/mol

9. Abhisar

got it ?
