2.00 M NaOH means that there are 2 moles of NaOH in each liter of solution
First, find how many moles of NaOH we have. Use this equation.
Molarity x Liters = Moles
Convert mL to L
7.58 mL x 1 Liter/1000mL = .00758 L
Set up the equation
2.00 M x .00758 L = .01516 moles
The molar mass of NaOH is 39.997 g
.01516 moles x 39.997 grams per mole = .60635452 rounded with significant figures to .606 grams of NaOH
Mg = 24.3 g/mol
23.5 g / 24.3 g/mol = 0.97 mol Mg
The answer is A. foliated
There can be two kinds of metamorphic rocks: foliated and non-foliated.
Foliated rocks are formed by intense pressure, squeezing their minerals so they become aligned. In contrast, non-foliated rocks do not form due to pressure.

Answer:
![m_{air}=3.6g](https://tex.z-dn.net/?f=m_%7Bair%7D%3D3.6g)
Explanation:
Hello,
In this case, given the law of conservation of mass which states that mass cannot be created nor destroyed, since the produced mass of the compound is 15.9 g and the mass of the initial substance is 12.3 g we obtain the mass of air by applying the following equation:
![m_{reactants}=m_{products}\\\\m_{substance}+m_{air}=m_{product}](https://tex.z-dn.net/?f=m_%7Breactants%7D%3Dm_%7Bproducts%7D%5C%5C%5C%5Cm_%7Bsubstance%7D%2Bm_%7Bair%7D%3Dm_%7Bproduct%7D)
Thus, solving for the mass of air we obtain:
![m_{air}=m_{product}-m_{substance}\\\\m_{air}=15.9g-12.3g\\\\m_{air}=3.6g](https://tex.z-dn.net/?f=m_%7Bair%7D%3Dm_%7Bproduct%7D-m_%7Bsubstance%7D%5C%5C%5C%5Cm_%7Bair%7D%3D15.9g-12.3g%5C%5C%5C%5Cm_%7Bair%7D%3D3.6g)
