Question

calcule o valor a massa molecular dos compostos abaixo
Dados:(H=1 , S=32 ,P=31 , N=14 e O= 16)​

A) H2SO4
B) HNO3
C) H4P2O7

Answer 1

a)

$\mathsf{H_{2}SO_{4}=2.1+32+4.16=2+32+64=98\,u}$

b)

$\mathsf{HNO_{3}=1+14+3.16=15+48=63\,u}$

c)

$\mathsf{H_{4}P_{2}O_{7}=4.1+2.31+7.16=4+62+112=178\,u}$
