Answer: 2.17 g of bromide product would be formed
Explanation:
The reaction of calcium bromide with lithium oxide will be:

To calculate the moles :

As lithium oxide is in excess, calcium bromide is the limiting reagent.
According to stoichiometry :
1 mole of
produce = 2 moles of 
Thus 0.0125 moles of
will require=
of 
Mass of 
Thus 2.17 g of bromide product would be formed
2.5 x 10^24 molecules of C4H10
D. 293
According to Charle’s law, with pressure being constant, an increase in volume will also increase the temperature. 10 degrees Celsius is 283 K, so you would need to find the number greater than 283 K which is 293 K.
