If 17.8 grams of KOH dissolve in enough water to make a 198-gram solution, what is the concentration in percent by mass?
sleet_krkn [62]
Solute of solution = 17.8 g

Solvn = 198 g

% = 17.8 / 198

w% = 0.089 x 100 = 8.9%  by mass

hope this helps!

A bottle of the antiseptic hydrogen peroxide is labeled 3.0% (v/v). How many mL of hydrogen peroxide are in a 400 mL bottle of t
zepelin [54]
There are several ways of expressing concentration of solution. Few of them are listed below
1) mass percentage
2) volume percentage
3) Molarity
4) Normality
5) Molality

In most of the drugs, concentration is expressed either in terms of mass percentage or volume percentage. For, solid in liquid type systems, mass percentage is convenient way of expressing concentration, while for liquid in liquid type solutions, expressing concentration in terms of volume percentage is preferred. Present system is an example of liquid in liquid type solution 


Here, concentration of H2O2 is given antiseptic = 3.0 % v/v

It implies that, 3ml  H2O2 is present in 100 ml of solution

Thus, 400 ml of solution would contain 4 X 3 = 12 ml H2O2

The enzyme, carbonic anhydrase, is a large zinc-containing protein with a molar mass of 3.00 x10^4 g/mol. Zn is 0.218% by mass o
tia_tia [17]

The mathematical expression for mass percent is given by:

Mass percent = \frac{mass of the compound}{molar mass of the compound}\times 100

Put the values,

0.218 percent of zinc = \frac{mass of zinc}{3.00 \times 10^{4} g/mol}\times 100

mass of zinc = 0.218 \times (3\times 100) g

= 0.654 \times 100 g or 65.4 g

Now, number of moles of zinc  =\frac{given mass in g}{molar mass of zinc}

= \frac{65.4 g}{65.38 g/mol}

= 1.00 mole

Number of atoms of zinc is calculated by the Avogadro number.

Now, according to mole concept

6.022\times 10^{23} molecules of enzyme consists of 6.022\times 10^{23} atoms of zinc

So, 1 molecule of enzyme contains  =\frac{6.022\times 10^{23}atoms of zinc}{6.022\times 10^{23} }

= 1 atom of zinc.

Hence, every carbonic anhydrase molecule consists of 1 atom of zinc.

If 8.700 g of c6h6 is burned and the heat produced from the burning is added to 5691 g of water at 21 °c, what is the final tem
leonid [27]
C₆H₆ is benzene which has a molar mass of 78 g/mol. When benzene is burned, the reaction is called combustion. The heat produced in this reaction is called the heat of combustion. For benzene, the heat of combustion is -3271 kJ/mol.

Heat of benzene = (8.7 g)(1 mol/78 g)(-3271 kJ/mol) = -364.84 kJ

By conservation of energy,
Heat of benzene = - Heat of water
where
Heat of Water = mCp(Tf - T₀)
where Cp for water is 4.187 kJ/kg·°C

Thus,

-364.84 kJ = -(5691 g)(1 kg/1000 g)(4.187 kJ/kg·°C)(Tf - 21)
<em>Tf = 36.31°C</em>
