Answer:

10.3

Explanation:

The pH of a substance is a number spanning from 0 to 14.

A substance with pH between 0 and 7 is said to be acid, while a substance with pH between 7 and 14 is said to be basic. A substance with pH of 7 is a neutral substance.

The pH of a solution can be calculated using the formula:

$pH=-log[H_3O^+]$

where

$[H_3O^+]$ is the concentration of hydronium ion in the solution

In this problem, we have a concentration of hydronium ion in the solution equal to

$[H_3O^+]=4.7\cdot 10^{-11} mol/L$

Therefore, we can apply the formula above to calculate the pH of the solution, and we find:

$pH=-log[4.7\cdot 10^{-11}]=10.3$

So, the pH of this solution is 10.3.

A solution was made by dissolving 5.10 mg of hemoglobin in water to give a final volume of 1.00 ml. the osmotic pressure of this

Assoli18 [71]

The molecular weight of hemoglobin can be calculated using osmotic pressure

Osmotic pressure is a colligative property and it depends on molarity as

πV = nRT

where

π = osmotic pressure

V = volume = 1mL = 0.001 L

n = moles

R = gas constant = 0.0821 L atm / mol K

T = temperature = 25°C = 25 + 273 K = 298 K

Putting values we will get value of moles

$moles=\frac{\pi V}{RT}=\frac{0.00195X0.001}{0.0821X298}mol$

we know that

$moles=\frac{mass}{molarmass}$

Therefore

$molarmass=\frac{mass}{moles}=\frac{5.10X10^{-3}g}{7.97X10^{-8}}=6.399X10^{4}g$

What is the mass percentage for copper ?

RideAnS [48]

Answer:

Explanation:

To find the mass percent composition of an element, divide the mass contribution of the element by the total molecular mass. This number must then be multiplied by 100% to be expressed as a percent.

What are the energy in a plant?

Vadim26 [7]

In plants, these energy factories are called chloroplasts. They collect energy from the sun and use carbon dioxide and water in the process called photosynthesis to produce sugars. Animals can make use of the sugars provided by the plants in their own cellular energy factories, the mitochondria.
