It means that 100mL of solution has 75g of solute dissolved in it.
To calculate the molarity of a solution, you first need to find the number of moles of the solute. In this case, the molar mass of CuSO4 · 5H2O is 249.68 g/mol. So, 75 g is equal to 0.3 moles (75g / 249.68 g/mol). Next, divide the moles of the solute by the volume of the solution in liters to get the molarity. In this case, the molarity is 0.3 moles / 1.0 L = 0.3 M.
To calculate the molarity, you first need to convert the grams of sugar to moles. The molar mass of sugar (sucrose) is about 342 g/mol. So, 15 g / 342 g/mol = 0.044 moles of sugar. Next, convert the volume of the solution to liters by dividing 200 ml by 1000 to get 0.2 L. Finally, divide the moles of sugar by the liters of solution: 0.044 moles / 0.2 L = 0.22 M. So, the molarity of the solution is 0.22 M.
0,044 moles of NH3 can be produced.

It is probably easiest to convert everything into grams here. 31000mg= 31g 7500cg= 75g (Assuming you mean centigrams) 1.7kg= 1700g So obviously 1.7kg is the largest.
75g is 75g
is 75g of 1kg
1000g = 1 kg ⇒ 75g = 75 ÷ 1000 kg = 0.075 kg
For practical purposes a gram and a millilitre are considered the same. So 100ml of icecream would be extremely close to 100 gm.
75 grams = 0.17 pounds
The number of stones in 75g would depend on the average weight of a stone. However, to give you an estimate, an average stone weighs around 5g. So, approximately, 75g would be equivalent to 15 stones.
The mass of the solution is 5g (iron sulfate) + 75g (water) = 80g. Therefore, the percentage by mass of iron sulfate in the solution is (5g / 80g) * 100% = 6.25%.
75g
There are 1,000 grams in a kilogram.800kg is equal to 800,000 grams.Therefore 800kg is greater than 75g.
Double 75g is 150g. This is calculated by multiplying 75 grams by 2, resulting in a total weight of 150 grams.
75g
The cost of 75g of butter would depend on the price per unit weight of butter at the store. To calculate the cost, you would need to know the price per gram or per ounce of butter. Once you have that information, you can multiply the price per unit weight by 75g to find the total cost of 75g of butter.
