Answer:
Explanation:
Given data:
Volume of solution = 1.5 L
Mass of solute = 61.2 g
Molar mass of solute:
= 23 + 14 + (16 × 3)
= 23 + 14 + 48
= 85 g/mol
Required:
Molarity = ?
Formula:
Solution:
First, we have to find moles of solute.
We know that,
Moles = mass / molar mass
Moles = 61.2 / 85
Moles = 0.72 moles
Now, finding molarity:
Molarity = 0.72 / 1.5
The molarity of the 1.5 L solution of sodium nitrate containing 61.2 g of NaNO3 is approximately **0.480 M**
To calculate the molarity (M) of a solution, you can use the formula:
- Volume of solution (\( V \)) = 1.5 L
- Mass of sodium nitrate = 61.2 g
- Molar mass of sodium nitrate = 85 g/mol (Na: 23 g/mol, N: 14 g/mol, O: 16 g/mol)
First, calculate the moles of sodium nitrate using its molar mass:
Now, substitute the values into the molarity formula:
So, the molarity of the 1.5 L solution of sodium nitrate containing 61.2 g of NaNO3 is approximately **0.480 M**.

Answer:
A
Explanation:
635 g
635 g/cm3
634.5 ml
Answer:
JUST B
Explanation:
The mass of 235 cm³ of aluminum, which has a density of 2.70 g/cm³, is calculated to be 634.5 g using the formula Mass = Density × Volume.
To find the mass of a given volume of a substance, you can use the formula: Mass = Density × Volume. In this case, the density of aluminum is given as 2.70 g/cm³ and you need to find the mass of 235 cm³ of aluminum.
Substitute the given values into the formula:
Mass = 2.70 g/cm³ × 235 cm³ = 634.5 g
Therefore, the mass of 235 cm³ of aluminum is 634.5 g.

(2) 100 K and 25 atm
(3) 400 K and 0.25 atm
(4) 400 K and 25 atm
Answer : The correct option is, (3) 400 K and 0.25 atm
Explanation :
The conditions for ideal gas are :
Ideal gas are those gas that has no intermolecular attractions.
Ideal gas are those gas that have negligible volume.
The ideal gas equation is,
The conditions for real gas are :
Real gas are those gas that have intermolecular attractions.
Real gas are those gas that have volume.
The real gas equation is,
A real gas behave ideally at high temperature and low pressure condition.
From the given options, option (3) have high temperature and low pressure is the correct option.
Hence, the 400 K and 0.25 atm conditions of temperature and pressure does a sample of neon behave most like an ideal gas.
The correct answer is A.syrup
