I^2 = -1
so,
-99 = -1*99 = i^2*99 = 99i^2
256, 340, 740, 740, 749, 999

Well, how do you find the measures of angles when you have a right angle and one angle measurement?
Answer:
70. g NaCl
Step-by-step explanation:
For every one mole of a substance, there is a molar mass that coincides with the values of the periodic table. NaCl has a molar mass of 58.44g (Na+Cl). You then take this molar mass and multiple it by the number of moles asked (1.2) to find the grams present.
58.44g * 1.2mol = 70.128g
Then you would round to 2 sig figs to get 70. g of NaCl
