A particular substance has a measured solubility in water of 3.6 g/1.0 L. How much of the substance can be dissolved in 650 L of
1 answer:
Answer : 2.34 kg or 2340 g can be dissolved in the given amount of water
The solubility of the substance is given as 3.6 g/1.0 L. That means 3.6 grams of the substance can be dissolved in 1 L of water.
We have 650 L of water. The equation can be set up as follows.
We can cancel out L here
Therefore we can say that 2340 grams or 2.34 kg of the substance can be dissolved in the given amount of water

<h3>Stoichiometic problem</h3>The equation for the complete combustion of C2H2 is as below:
The mole ratio of C2H2 to O2 is 2:5.
1 mole of a gas at STP is 22.4 L.
At STP, 100.50 mL of C2H2 will be:
100.50 x 1/22400 = 0.0045 mole
Equivalent mole of O2 according to the balanced equation = 5/2 x 0.0045 = 0.01125 moles
0.01125 moles of O2 at STP = 0.01125 x 22400 = 252.0 mL
Thus, 252.0 mL of O2 gas will be required at STP.
