Answer:
0.332mL
Explanation:
11.4g/mL is 11.4 for every one mL
11.4g / 1mL needs to be the same ratio as 3.78g to an unknown value, let's call it x.
11.4g/1mL = 3.78g/x
We cross multiply: 1*3.78 = 11.4*x
3.78 = 11.4x
Now isolate x by diving 11.4 on both sides: 0.331578974mL = x
In chemistry, we usually round to significant figures, so our answer would be 0.332mL
