Answer:
88.7 grams of water is equal to 0.0887 liters.
Explanation:
1000 grams of water is equal to 1 liter
88.7/1000= 0.0887 liters
This particular object can be measured with either a rigid or flexible measuring tool. Feet and yards are measured on both a yard stick and a tape measure, and meters are measured on meter sticks and most tape measures.
Solution:[tex]Let the molar mass of metal M is 'a',\\
\rn(so)\\
\frac{M_{o}}{2M_{H}+2M_{o}+a} =\frac{2.16}{2.1+2.16+a} =0.328\\
By simple algebric calculation. We get,\\ a=63.56g/mol\\
\rn(Now,)\\
We have to confirm which metal has the molar mass of 63.56g/mol. By using periodic table we have to find it the we get it is Copper(Cu).
Here we have to calculate the number of moles of valuable propane can be prepared from 1.8 moles of carbon.
From 1.8 moles of carbon 0.3 moles of propane can be prepared by the reaction.
From 6 moles of carbon (C) 1 moles of valuable propane (C₃H₈) can be prepared.
Thus from 1.8 moles of C we can obtain
×1.8 = 0.3 moles of the propane can be prepared.
Thus the amount of propane produced in this reaction is determined.
The % mass/mass concentration of solute in the seawater sample is calculated as below
% mass = mass of the solute /mass of the solvent(sea water) x100
mass of the solute =1.295 g
mass of the solvent(sea water_) = 25.895 g
there the % mass = 1.295/25.895 x100 = 5.001 %
