The answer that the homework assigned wanted was (580 cal/g)(400g) = 232,000 cal = 971,105.60 J Heat Transfer equation: q=mc(dT) Energy = (mass) x (specific heat) x (change in temp) m = 400 grams c (of H20) = 4.186 Joules/gram (you just look up this value) dT = 100°C-25°C (assume water evaporates at 100°C, so change in temp is T(final) - T(initial) q = 400g x 4.186J/g x 75°C q= 125,580 J = 125.6 KJ
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.
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
