Amount of money that Cheryl has = $56
Cost of each notebook = $1.60
The maximum number of notebooks she can buy = n
Then
n = 56/1.6
is the inequality that shows the maximum number of notebooks she can buy with her money
On solving the inequality, we get
n = 35 notebooks.
It would be: 1s2, 2s2, 2p4
Answer:
well what I think is that C is the correct answer
Answer:
Both molarity and formality express concentration as moles of solute per liter of solution. Formality is a substance's total concentration in solution without regard to its specific chemical form. ... The formality of a solution is defined as the number of formula mass of any solute dissolved in 1 litre of solution.
Moles = 15.5 g / 40 g/mol = 0.3875 mol
M = 0.3875 mol / 0.250 L = 1.55M
