If 34.9g of water is measured out, how many moles is that?

1.94 moles

Explanation:

because moles =mass/mr

=34.9/18

which gives 1.938 so we round it up to 1.94

mr of H2O is 18

hope this helps :)

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.
