Question

Molecular mass of H2SO4 NACL KNO3

Answer 1

Answer:

H2So4-2+32+16+16+16+16=98

Explanation:

nacl-58. 5 kno3-100

Answer 2

Answer:

mass of

1. hydrogen = 1 u

2. sulphur = 32 u

3. oxygen = 16  u

4. sodium = 23 u

5. chlorine = 35.5 u

6. potassium = 39 u

7. nitrogen = 14 u

molecular mass of  H2SO4 = 2(1)+32+4(16)= 98 u

molecular mass of nacl = 23+ 35.5 = 58.5 u

molecular mass of KNO3 = 39 + 14 + 3(16) = 101 u
