Molar mass of c16h19n305s
Masja [62]

Answer:

365.212

Explanation:

According to the given situation, the calculation of molar mass is shown below:-

Data provided

c_{16}\ h_{19}\ n_3\ o_5\ S

Molar mass = 16 × 12 + 19 × 1.008 + 3 × 14 + 5 × 16 + 32.06

= 192 + 19.152 + 42 + 80 + 32.06

Molar mass = 365.212

Therefore for determining the molar mass we simply solve the above equation.

So, the correct answer is 365.212

Sodium Chloride (NaCl) has a molecular mass of 58 grams/mole. What is the molarity of a NaCl solution with a
Vera_Pavlovna [14]

Answer:

2nd option

Explanation:

Molarity is the number of moles of the solute (NaCl) in 1 litre of the solution (NaCl solution).

Given: concentration= 232g/ L

what we are trying to achieve is __mol/ L.

So in 1 litre, we have 232g of NaCl.

To convert mass to mole, we divide it by the Mr.

Given that the Mr is 58g/mol,

number of moles

= 232 ÷58

= 4

Thus, 1 litre has 4 moles of NaCl.

Therefore, the molarity is 4.0 mol/L.
