Answer: \frac{1mol}{159.7g} or \frac{159.7g}{1mol}

Explanation: Given molar mass of Iron(III)oxide is 159.7 g/mol. It means the mass of 1 mol of Iron(III)oxide is 159.7 g.

How to write the molar mass as a conversion factor is all depends if we are calculating the moles or grams.

If the grams are given and we are asked to calculate the moles then the conversion factor is written as \frac{1mol}{159.7g} and if the moles are given and we are asked to calculate the grams then the conversion factor is written as \frac{159.7g}{1mol} .

For H3PO4, Ka1 = 7.3 x 10^-3, Ka2 = 6.2 x 10^-6, and Ka3 = 4.8 x 10^-13. A 0.10 M aqueous solution of Na3PO4 therefore would be
zmey [24]

Answer:

The aqueous solution of Na_{3} Po_{4} therefore would be "strongly basic."

Explanation:

Strongly basic because the Na_{3} Po_{4} is completely an ionic compound. These compound can be 100% splitted into metal ions and hydroxide ion when used in the aqueous solution. Each moles dissolves which can give rise to mole of hydrogen ions when used in the solution. Whereas strong bases are not soluble in water as well.  in the presence of water equilibrium can also be achieved. A strong base has the capability which can just remove the proton from the molecule.

A non-mechanical, rigid, and fully insulated mixing tank is used to combine two inflows to produce wet steam. One inflow consist
Bogdan [553]

Explanation:

As it is given that stream A is super heated. From stream tables, we get that specific enthalpy, (h_{A}) is 3054.29 kJ/kg.

For stream B, it is saturated water at 25 degree celsius. It's h_{B} is 2546.54 kJ/kg.

Stream C, data will be as follows.

                P = 200 kPa,         \chi = 0.9

So, h_{c} = h_{f} + \chi \times h_{fg}  

        = 504.47 + 0.9 \times 2201.7

        = 2486 kJ/kg

Now, energy balance formula will be as follows.

            m_{A}h_{A} + m_{B}h_{B} = (m_{A} + m_{B})h_{c}

              3 \times 3054.29 + m_{B} \times 2546.54 = (3 + m_{B}) \times 2486

             m_{B} = 28.16 kg/s

Hence, inflow of saturated liquid is 28.16 kg/s. According to steam table, temperature of wet steam is 120.23^{o}C

Mass flow rate of out flow is 31.16 kg/s.

A. Phenol (C6H5OH) is an aromatic compound and a colourless liquid widely used in household products
Olin [163]

Because there are 2 Cl on the left, we will put a coefficient 2in front of HCl on the right side to balance out the Cl. This would result in an unequal amount of H, with 6 on the right side and 7 in the left, so we have to put a coefficient of 2 in front of C6H5OH and C6H4OH on both sides to balance out the H. By doing this, we would obtain an equal amount of H on both sides. The Carbon is already balanced, and so is the Oxygen.
