kiya koi muje bata sakta he/chemistry

[crystal hear]

kiya koi muje bata sakta he k agar hum kisi reactant ka mass maloom he to hum product ka mass kese nikalte he pleeease

Quiet simple bhai.... reactant k mass ko plus karo product ka mass mil jaiga like ek example hai:

Zn + S --> ZnS
65.4g 32g
as mein reactant Zn ka mass hai 65.40 and reactant S ka mas hai 32...
ab an dono ko plus karo 65.40+32=97.40g

ye 97.40 apka product ka mass hai..

agar kuch na samajh aai to fell free to ask

Pentane is burned in an excess of oxygen to produce carbon dioxide and water. If
144 g of pentane are burned, how many grams of carbon dioxide are produced?

[Alisweet]

bhai dekhein pentene ka chemical formula hai C5H10

now pentene is burned in an excess of oyegen
C5H10 + O2 ----> CO2 + H2O
70g 32g 44g 18g


Now jo formula lagta hai jo 1st year mein hai stoichiometry wale formulas lagte hain wo lagao.. wo mujhe yad nahi hain ab
