The relative atomic mass of "M" is 6.94. The metal is lithium. > 1. Calculate the moles of "N". Assume that we have 0.673 g of "N". Then we have 1 g of "M" and 1.673 g of "M"_3"N". …

The formula tells us that there are 5 moles of water for every 1 mole of CuSO4, so the mass of water would be 5 x 18 g (where 18 is the molecular mass of water). The total mass of the …

calculate moles of Acid, calculate moles of Base. subtract, #OH^-# should be in excess, calculate Molarity of #OH^-# , pOH = -log (#OH^-#), then 14-pOH = pH

Since both #"HA"# and #"A"^"-"# are in the same solution, the ratio of their moles is the same as the ratio of their molarities. We can use the Henderson-Hasselbalch equation to calculate the …

A mixture of ethene and propene requires 3 mol of oxygen for complete oxidation and 20.16 L of hydrogen for complete reduction. What is the mass of the original mixture? Chemistry

The reactants are present in equivalent amounts. We will use the moles of #"KOH"# in our calculations. Step 3. Calculate #q_1# #q_1 = nΔ_text (rxn)H = "0.027 84"Δ_text (rxn)Hcolor …

A student reacted 0.2200 g of zinc (Zn) with excess hydrochloric acid (HCl) to generate hydrogen gas (H2) in a 25°C laboratory. Given that the pressure of the gas is 0.80 atm and R = 0.0821 …

Step 3. Calculate the moles of gas The Zerewitinoff reaction is a quantitative chemical test for the determination of acidic hydrogens in a compound. Acidic hydrogens include terminal alkynes, …

when we deal with the raoult's law equation for an ideal solution of 2 ideal liquids which are volatile, do we have to use the number of moles at equilibrium to calculate the mole fraction of …
