What mass of glucose (C6H12O6) should be dissolved in 10. 0 kg of water to obtain a solution with a freezing point of -4. 2 ∘C?.

Answers

Answer 1

Answer:

4.1kg

Explanation:

I dont kwon but it was ok in the test

Answer 2

The mass of glucose dissolved in the solution is obtained as 4.734 Kg.

We know that;

ΔT = K m i

ΔT = Freezing point depression

K = freezing constant = 1.86 °C/m

m = molality of solution  

i = Van't Hoff factor = 1 (molecular solution)

To find the freezing point depression;

Freezing point depression = Freezing point of pure solvent - Freezing point of solution

Since freezing point of water = 0°C

Freezing point depression = 0°C - (-4. 2 ∘C) = 4. 2 ∘C

The molality of the solution is obtained as follows;

m = ΔT/K i

m = 4. 2 ∘C/ 1.86 °C/m × 1

m = 2.63 m

Molality = number of moles/mass of solvent in Kg

Number of moles = mass/molar mass =

Molar mass of glucose = 180 g/mol

Let the mass of solute be m

2.63 = m/180/10

2.63 = m/1800

m = 2.63 × 1800

m = 4734 g or 4.734 Kg

A car is traveling with a constant speed when the driver suddenly applies the brakes, causing the car to slow down with a constant acceleration of magnitude 3. 50 m/s2. If the car comes to a stop in a distance of 30. 0 m, what was the car's original speed?.

Answers

Answer: 14.49 m/s

Explanation:  you would have to use  kinematic equations to solve for the original speed.

v^2 = v0^2 + 2 (a) (x)  where v = 0 since the car stopped

then you would get v0 = sqrt (2(a)(x))

plug in the known values

v0 = sqrt(2(3.50)(30.0))

v0 = 14.49 m/s

So the answer would be 14.49 m/s

What is Disributive property?

We can divide anything into portions when you distribute it. The distributive property in mathematics breaks down expressions into the sum or difference of two integers, which makes it easier to solve complex problems.

This concept states that multiplying the sum of two addends by a number will produce the same outcome as multiplying each addend separately by the number and then adding the results.

The distributive property, sometimes known as the distributive property of multiplication, tells us how to solve certain algebraic expressions that include both multiplication and addition.
