a)
\(\dfrac{M_X}{M_{H_2}}=18\\ \Rightarrow M_X=18.2=32\left(\dfrac{g}{mol}\right)\)
`X:O_2`
b)
\(\dfrac{M_Y}{M_{H_2}}=15\\ \Rightarrow M_Y=15.2=30\left(\dfrac{g}{mol}\right)\)
`Y:NO`
c)
\(\dfrac{M_Z}{M_{H_2}}=32\\ \Rightarrow M_Z=32.2=64\left(\dfrac{g}{mol}\right)\)
`Z:SO_2`
d)
\(\dfrac{M_T}{M_{kk}}=1,517\\ \Rightarrow M_T=1,517.29=44\left(\dfrac{g}{mol}\right)\)
`T:CO_2`
e)
\(\dfrac{M_U}{M_{kk}}=2,759\\ \Rightarrow M_U=2,759.29=80\left(\dfrac{g}{mol}\right)\)
