How many moles of HCOONa must be added to 1L of 0.1 M …
WebAnd so the first thing to think about is, in our reaction for every one mole of carbon monoxide, we use two moles of molecular hydrogen, and then that produces one mole … Web19 feb. 2024 · Now, in the given question, to get the equal number of molecules as that of 2 moles of \[{H_2}O\], we would need exactly two moles of methanol. Molecular weight of methanol is equal to 32 g i.e. Weight of one mole of methanol = 32 g Hence, weight of two moles of methanol = 2 $\times$ 32 g = 64 g Thus, the correct answer is 64 grams. WebIt is clear that for 1 mol of Na 2 CO 3 2 mol of HCl is required, similarly for 1 mol of NaHCO 3 1 mol of HCl is required. So number of moles required of HCl = 2(0.00526) + 0.0053 = … dickeys thanksgiving feast
