Calculate the energy in joules and calories required to heat 25.0 g of water from 12.5C to 25.7C

Chemistry
1 answer:
Alex Ar [27]3 years ago
8 0
The heat (Q) required to raise the temp of a substance is:<span>Q=m∗Cp∗ΔT</span><span> where m is the mass of the object (25.0g in this case), Cp is the specific heat capacity of the substance (for water Cp = 1.00cal/gC, or 4.18J/gC,
and Dt is the change in temp.
You'll have to solve this twice, once with the Cp in calories, and once with the Cp in joules.
</span><span>1380.72 Joules</span>

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

SEP Engaging in Argument A classmate claims that sodium is a significant
blondinia [14]

Sodium is not a macromolecule hence it does not contain any calories.

<h3>Does sodium contain calories?</h3>

The term  calorie is a unit of energy. We often us the term to describe the amount of energy that is contained in each kind of food. The higher the calories, the greater the energy that the food contains.

Calories can only be contained by macromolecules such as proteins, carbohydrates, fats etc. Sodium is not a macromolecule hence it does not contain any calories at all hence the classmate is wrong.
