How many moles are there in 25.0 grams of kmno4

There are 0.158 moles of in 25.0 g of

Explanation:

Molar mass of is 158.034 g/mol

So, mass of 1 mol of is 158.034 g . Therefore number of moles of in 25.0 g sample is moles or 0.158 moles.

It should be remembered that, number of moles=

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
