Answer:
0.01981 gallons.
Explanation:
In this problem, we need to convert 75 mL of water to gallons.
We know that, 1 gallon = 3785.41 mL
To convert 75 mL to gallons, we must use to the unitary method such that,
1 mL = (1/3785.41) gallon
So,
So, there are 0.01981 gallons in 75 mL of water.
Answer:
Explanation: the molar mass of the whole compound is 223.35u
now make ratios for each of the elements and multiply by 100%
copper= 63.55/223.35 x 100 % comp of copper is 28.45%
bromine= (79.9x2)/223.35 x 100 %comp of bromine is 71.54%
multiply bromines molar mass by 2 when calculating
Exothermic as energy is being released by the reaction
