Please answer the attached question by selecting of the the given answers.
hichkok12 [17]

Answer:

C

Step-by-step explanation:

Given that Q varies inversely as the square of p then the equation relating them is

Q = \frac{k}{p^2} ← k is the constant of variation

To find k use the condition Q = 36 when p = 7

k = Qp² = 36 × 7² = 36 × 49 = 1764

Q = \frac{1764}{p^2} ← equation of variation

When p = 6, then

Q = \frac{1764}{6^2} = \frac{1764}{36} = 49 → C

Convert 1.2 moles of NaCl (table salt) to grams.
olga_2 [115]

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
