Question

HALLAR LA MASA MOLECULAR DE:
1. Na1 (As1 O3) = Na=23 , As=74,92 , O=16

2. Mn 1O3 = Mn =54,94 , O=16………. g/mol


3. H1 Cl1 O4 = H=1 ,Cl=35,45 , O=16

Answer 1

Respuesta:

1. 145.92

2. 102.94

3. 100.45

Explicación:

1. Na * 1 = 23 * 1 = 23

As * 1 = 74.92 * 1 = 74.92

O * 3 = 16 * 3 = 48

Luego sumas: 23 + 74.92 + 48 = 145.92

2. Mn * 1 = 54.94 * 1 = 54.94

O * 3 = 16 * 3 = 48

Luego sumas: 54.94 + 48 = 102.94

3. H * 1 = 1 * 1 = 1

Cl * 1 = 35.45 * 1 = 35.45

O * 4 = 16 * 4 = 64

Luego sumas: 1 + 35.45 + 64 = 100.45
