mole × molecular weight = mass (rearrange the equation) mass = molecular weight × mole As 1.626×1023 molecules of NaOH is also equal to 0.27 moles, and we know that the molecular weight of NaOH is 40, we can use these numbers to get: mass = 40 × 0.27 = 10.8 g So we now know...

更新1: Uncle Michael ( 博士级 1 级 ) : 头二绦我都明呀 thx =) 但第三条打错了 can you explain to me ? 3. Consider the following equation: X2 (g) + 3Y2(g) ---> 2XY3 (g) If 4 moles of X2 (g) react with 6 moles of Y2 (g) What is the number...
Define Partial mole. Partial mole synonyms, Partial mole pronunciation, Partial mole translation, English dictionary definition of Partial mole. Noun 1. hydatidiform mole - an abnormality during pregnancy; chorionic villi around the fetus degenerate and
To find the mole ratio in stoichiometry, the chemical equation for a reaction must first be balanced. Once the chemical equation is balanced, then the coefficients tell the ratios with which the different substances in the reaction will react. An example of a ratio would be 2 moles H2/1 mol...
