A mass of the crucible (g) 88.000g

1 answer:

4 0

A)5.000g
b)mole=mass/molarmass
   molar mass of H2O=18g
   mass of water=5g
b)mole of water=5.000/18.000=0.2778g
c)mass of salt=2.342g
d)mole of salt=mass/molar mass
   pure salt is NaCl
   molar mass of NaCl=58.50g
d)mole of salt=2.342/58.5=0.040mol
e)mole ratio=0.27:0.04

compound 1 contains 15.0g of hydrogen and 120.0g oxygen. What is the percent compound of each element?

allsm [11]

Note down the formula below

$\boxed{\sf Mass\%\;of\; element=\dfrac{Mass\:of\:the\: element}{Mass\;of\:the\: compound}\times 100}$

Mass of the compound

$\\ \sf\longmapsto 15+120=135g$

Mass % of Hydrogen:-

$\\ \sf\longmapsto \dfrac{15}{135}\times 100$

$\\ \sf\longmapsto \dfrac{1}{9}\times 100$

$\\ \sf\longmapsto 11.1\%$

Mass % of Oxygen:-

$\\ \sf\longmapsto \dfrac{120}{135}\times 100$

$\\ \sf\longmapsto \dfrac{8}{9}\times 100$

$\\ \sf\longmapsto 88.9\%$
