Saline solutions (nacl in water) used to deliver intravenous drugs are 0.89%(w/v). what mass of nacl is found in 200 ml of such

Gnom [1K]

A ratio of 0.89% w / v or 0.0089 in fraction means that there is 0.89 weight of NaCl pero volume of solution. Therefore the mass of NaCl is:

mass NaCl = 0.0089 * 200

mass NaCl = 1.78 grams

A 0.753 g sample of a monoprotic acid is dissolved in water and titrated with 0.250 M NaOH. What is the molar mass of the acid i

Alexeev081 [22]

Answer:

$MM_{acid}=140.1g/mol$

Explanation:

Hello,

In this case, since the acid is monoprotic, we can notice a 1:1 molar ratio between, therefore, for the titration at the equivalence point, we have:

$n_{acid}=n_{base} \\\\V_{acid}M_{acid}=V_{base}M_{base}\\\\n_{acid}=V_{base}M_{base}$

Thus, solving for the moles of the acid, we obtain:

$n_{acid}=0.0215L*0.250\frac{mol}{L}=5.375x10^{-3}mol$

Then, by using the mass of the acid, we compute its molar mass:

$MM_{acid}=\frac{0.753g}{5.375x10^{-5}mol} \\\\MM_{acid}=140.1g/mol$

Regards.
