Answer:
4) 1.5 mol
Explanation:
Well, the equation is already balanced and the mole to mole ratio of reactants and products are all 1. So if the limiting reactant is HCl and you have 1.5 mol, you do the mole to mole ratio with NaCl and since it is 1 to 1, there'd be 1.5 mol of NaCl.
Mass = number of mol x molar mass
Mass = 0.28mol x 55.8g/mol
Mass = 15.624g
The time of day the plants are watered is the independent variable. Keera did everything else the same for each plant.
