Web6 dec. 2007 · A 1 molar solution by definition is 1 mole of something, in this case glucose, in 1 liter of solution. The molecular weight of something can be found on the perdiodic table. The weight listed on the periodic table is the grams in a mole, these of course are for atoms. 12 H + 6 C +6O + 188.1558 grams in a mole of glucose. WebIn this case, logic dictates (and the factor-label method supports) multiplying the provided amount (mol) by the molar mass (g/mol): 9.2×10^−4molAr (39.95g/molAr)=0.037g Ar The result is in agreement with our expectations, around 0.04 g Ar. What is the mass of 2.561 mol of gold? Answer: 504.4 g 2.561 mol Au x 96.96g/1mole = 504.4g WebExplanation: To get the molarity, you divide the moles of solute by the litres of solution. Molarity = moles of solute litres of solution. For example, a 0.25 mol/L NaOH solution contains 0.25 mol of sodium hydroxide in every litre of solution. To calculate the molarity of a solution, you need to know the number of moles of solute and the total ... fisher and paykel 8kg condenser dryer
