Answer:
0.0894 M
Explanation:
So you first want to change the grams into moles (since molarity is moles solute per Liter solution).
The molar mass of NaNO3 is 84.995 g/mol, so we divide 0.38g of NaNO3 by 84.995 g/mol to get approximately 0.004471 mol NaNO3.
Now, all you have to do is to divide by the total Liters of water (your solution).
Since the volume is expressed in mL, you just need to divide by 1000 (1 L = 1000mL) to get 0.050 L solution.
Therefore, to get molarity, you divide 0.004471 mol by 0.050 L to get your answer of 0.0894 M.
There are two types of chemical compound one is covalent compound and another is ionic compound in chemistry. In ionic bonds, electrons are completely transferred. The correct option is option C.

What is chemical Compound?</h3>
Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
During formation of a compound calcium act as cation as Ca²⁺ so, if any element has to react with this cation in a 1:1 ratio, must have -2 charge over it . Option C represents S⁻², which react with Ca²⁺.
Therefore, the correct option is option C.

Answer:
Explanation:
NO is limit reactant so:
1÷7×46=6.57 grams of NO2 will form
Answer:
The answer to your question is V2 = 66.7 ml
Explanation:
Data
Volume 1 = V1 = 400 ml
Pressure 1 = P1 = 1 atm
Volume 2 = V2 = ?
Pressure 2 = P2 = 6 atm
Process
1.- To solve this problem use Boyle's law
P1V1 = P2V2
-solve for V2
V2 = P1V1 / P2
-Substitution
V2 = (1)(400) / 6
-Simplification
V2 = 400 / 6
-Result
V2 = 66.7 ml
