so in a) you have H2O, so you have 2 moles hyrdogens per 1 mole of H2O, so you have 2 x 4.67 = 9.34 moles of hydrogen b) 3 x 8.39 = 25.17 moles of Hc) 0.117 x 4 = 0.468d) 35.8 x 22 = 787.6seems difficult but it’s actually really easy!... Show More

use the equation moles = mass/molar mass Molar mass you get off your periodic table and your mass is given. Molar mass is the sum of the molar lots of the climate interior the question i.e molar mass of NaCL = molar mass of Na + Molar mass of Cl. you need to have the means to do the calculations now....
