Question

Me pueden ayudar por favor. ​

Answer 1

Explicación:

1. NaCl

Na = 23

Cl = 35

MM = 23 + 35 = 58 g/mol

2. Ca(OH)2

Ca = 40

O = 16

H = 1

MM = 40 + 16(2) + 1(2) = 40 + 32 + 2 = 74 g/mol

3. F2

F = 19

MM = 19 × 2 = 38 g/mol

4. CH3 - CH2 - CH3

C = 12

H = 1

MM = 12(3) + 1(8) = 36 + 8 = 44 g/mol

5. NaHCO3

Na = 23

H = 1

C = 12

O = 16

MM = 23 + 1 + 12 + 16(3) = 23 + 1 + 12 + 48 = 84 g/mol

6. Al(HSO4)3

Al = 27

H = 1

S = 32

O = 16

MM = 27 + 1(3) + 32(3) + 16(4)(3) = 27 + 3 + 96 + 192 = 318 g/mol

7. NH4NO3

N = 14

H = 1

O = 16

MM = 14(2) + 1(4) + 16(3) = 28 + 4 + 48 = 80 g/mol

8. H2O

H = 1

O = 16

MM = 1(2) + 16 = 2 + 16 = 18 g/mol

Espero haberte ayudado. :)
