According to the Wikipedia article on sucrose, the solubility of sucrose in water is 2000g/L at 25 degrees Celsius. Because the density of pure water is 1g/mL, 200 grams of pure water would be 200mL of water, which in turn is 0.200L of water. 2000g/L sucrose x 0.200L water = 400g of sucrose So, at 25 degrees Celsius, 400g of sucrose can dissolve in 200g of water.
The cost of sulfur varies depending on factors like purity and quantity, but it is typically priced per ton (1,000 kilograms) in industrial settings. Retail prices for small quantities may be listed per pound or kilogram in consumer markets.
To calculate the heat required to evaporate 400 g of water at 25 degrees Celsius, you would use the formula: Q = m * L. Where Q is the heat energy, m is the mass of water (400 g), and L is the heat of vaporization for water (2260 J/g). Plug in the values and calculate to find the heat required.
To make a 10N NaOH solution, you would need to dissolve 400g of NaOH pellets in enough water to make 1 liter of solution. This is because the molarity of a solution is calculated by dividing the number of moles of solute by the volume of solution in liters. Since NaOH has a molar mass of 40g/mol, 400g of NaOH would be equivalent to 10 moles, resulting in a 10N solution when dissolved in 1 liter of water.
2kg and 400g
What percentage of 400g is out of 2kg
1kg = 1000g 400g x 1kg/1000g = 0.400kg
Find how many R's are in 1G (If you divide 4 by 1000 you get .004 per G) Multiply your answer by the G's (400) to get total R's. (.004R x 400G) I get an answer of 400G=1.6R
400g
Its too easy my friend. 3 percent of 400 gram = 3 x 400g/100=12g
These ingredients will make 24 or more but oh well 400g Flour 400g Butter/Margarine 400g of Castor Sugar 4 Eggs Little bit of milk 1tsp Vanilla Essence
400g is 0.4kg
I have a 400g can here, 110mms
That is 14.11 ounces
400g
400g = 0.4kg
