Moles of ZnSO4 = Mass/Mr
= 2/(65.4 + 32.1 + (16 x 4))
= 0.012383.... mol
Since there is no chemical equation provided, I will assume that the ratio of ZnSO4:Li2CO3 is 1:1
Therefore there are 0.012383 mil of Li2SO4 as well
So the mass would be Moles x Mr = 0.012383.... x ((6.9 x 2) +32.1 + (4x16))
= 1.360 g of Li2SO4 produced
What stress would adding a postage stamp have on a helicopters flight capabilities?
Answer:
Bases
Explanation:
Most soaps fall under the base category as they are slippery and will taste bitter if you taste it (DONT TRY IT THO).
The mass of the balloon decreases as the release of hydrogen gas.
<h3>Mass of hydrogen and percent change</h3>
If the balloon had expanded more then the mass of hydrogen gas will increase inside the balloon but the mass of the balloon decreasing because the hydrogen gas escape from the system means from the balloon.
There is less percent change in the mass of the balloon while on the other hand, the concentration of hydrogen gas increases inside the balloon which leads to expansion of balloon so we can conclude that the mass of the balloon decreases as the release of hydrogen gas.

6+2=8 quarts of a new solution
0.45*6 - quarts antifreeze in <span>a solution that is 45% antifreeze
0.19*2 - </span>quarts antifreeze in a solution that is 19% antifreeze
x- concentration of a new solution
8x - quarts antifreeze in a new solution
0.45*6 + 0.19*2 = 8x
3.08=8x
x= 0.385 =38.5 %
