. Divide 94.20 g by 3.167 22 mL.
jeka94
94.20 g/3.16722 mL = 29.74 g/mL

The ratio of mass to volume is equal to the substance's density. Thus, 29.74 g/mL is the density of whatever substance it may be. Density does not change for incompressible matter like solid and some liquids. Although, it may be temperature dependent.

what is 31/50000 If the toxic quantity is 1.5 g of ethylene glycol per 1000 g of body mass, what percentage of ethylene glycol i
Sveta_85 [38]

Answer:

\%m=0.15\%

Explanation:

Hello,

In this case, we are asked to compute the by mass percent representing the toxicity of ethylene glycol in the body mass. In such a way, since the by mass percent is computed with the shown below formula:

\%m=\frac{m_{ethylene \ glycol}}{m_{ethylene \ glycol}+m_{body\ mass}}*100\%

We can use the given masses to obtain:

\%m=\frac{1.5g}{1.5g+1000g}*100\%\\ \\\%m=0.15\%

Best regards.

Acetic acid, ch3cooh, is a weak organic acid, pka 4.47. determine the position of the equilibrium for the reaction of acetic aci
Alexeev081 [22]

Acetic acid (CH3COOH) is a weak acid while methylamine (CH3NH2) is a weak base. During an acid base reaction, an acid tends to lose a proton while a base tends to accept a proton. The reaction at equilibrium is as follows:

CH3COOH +CH3NH2↔CH3COO^{-} +CH3NH3^{+}

Hence the species in equilibrium are:

Acetate anion: CH3COO-

Methyl ammonium cation: CH3NH3+
