<span>It is higher than the pressure on the outside of the bottle.</span>
Dilution formula:
mv = MV
where one side is concentration × volume BEFORE dilution and the other side is concentration × volume AFTER dilution.
(100mL) × (12 M) = (500mL) × (X)
(1200 M·mL) = (500mL) × (X)
(1200 M·mL) / (500mL) = X
2.4 M = X
Static. Is the bond if u need 2 know
The oxidation number of P in Mg3P2 is 3. When writing ionic compounds, you swap the oxidation numbers and add them as the subscript.
Answer:
68g/mol
Explanation:
The formula of ammonium sulfide is:
Ammonium sulfide = (NH₄)₂S
The molar mass of a compound is the mass in gram of one mole of the substance. In a compound, it is expressed gram formula mass or gram-molecular weight.
It is determined by the addition of the component atomic masses and then expressed in grams;
Atomic mass of N = 14, H = 1 and S = 32
(NH₄)₂S = 2[14 + 4(1)] + 32 = 36 + 32 = 68g/mol
