Hydrogen nitrate has a mass of 63.01 g/mol. In order to find the number of moles you divide the grams by the molar mass. 250/63.01 = 3.96 mol.
Compared to 250 g of gaseous nitrogen 250g of liquid nitrogen has greater density, viscosity, surface tension, and commercial value.
A copper sulphate solution can have different concentrations depending on how much copper sulphate crystals have been added into the water. A typical 1 molar solution of copper sulphate would need 250g of CuSO4, mixed with 700ml of H2O, with 10ml of H2SO4 added with another 290ml of water.
The 1st Law of Thermodynamics states that matter, and thus energy, cannot be created or destroyed; it can only be converted to different forms. To answer your question then, the mass of the products should always equal the mass of the reactants.
Balanced equation first. 2Al + 3H2SO4 >> Al2(SO4)3 + 3H2 ( only onfo on H2SO4 and it does say; ' completely reacted. ' So, H2SO4 limits and drives the reaction )( if it did not say this you would have to find mol Al and see what limits ) 250 grams H2SO4 (1mol H2SO4/98.086g )(1mol Al2(SO4)3/3mol H2SO4 )(357.17g/1mol Al2(SO4)3 ) = 303 grams of Al2(SO4)3
If it's pure water, 250mL of water will have a mass of 250g. 250g / 18gmol-1 = approx. 14mol.
Weight of NaCl used (250g)/Total molecular weight x Avagadro's number = total molecules of NaCl.
250g 250g
250g 250g are in one cup
It is: 2000g+250g = 2250 grammes
250g of cream cheese would be the best.
3.5kg = 3500g 3500g / 250g = 14 Therefore, 3.5kg will make 14 bags of 250g sweets
15% of 250g = 37.5g
250g
250g = 1/4kg
Yes, 250g of powder is greater than 850mg.
