What is the molarity of 0.945 L of a solution that contains 0.227 moles of Fe(NO3)3?

Chemistry
1 answer:
Wewaii [24]3 years ago
4 0

Answer:

0.2402 M

Explanation:

0.945 L sol contains = 0.227 moles

1 L sol will contain = (0.227/0.945)*1 = 0.2402 moles

Molarity = 0.2402 moles/L or M

Dr. Terror has developed a new alloy called Ultranomium. He is testing a bar that is 1.25 m1.25 m long and has a mass of 382 g.3
MrRissso [65]

Answer:0.8742j/g°C

Explanation: SOLUTION

GIVEN

length of bar=1.25m

mass 382g

temperature= 20°C to 288°C

Q=89300J

Specific Heat Capacity  will be calculated using

Q=mC∆T

where

C = specific heat capacity

Q = heat

m = mass

Δ T = change in temperature

C=Q/ m∆T

=89300/382X(288-20.6)

=0.8742j/g°C

The concentration of hydrogen in soil sample 13 * 10 ^ - 6 * M the soil is tested with a pH meter, what value should the meter r
vovikov84 [41]

Answer:

pH = 4.9

Explanation:

Given data

[H⁺] = 13 × 10⁻⁶ M

The pH is a scale used to determine <em>the acidity or basicity of a solution</em>. The pH is related to the concentration of hydrogen ions through the following expression.

pH = -log [H⁺]

pH = -log 13 × 10⁻⁶

pH = 4.9

Since the pH < 7, the soil is considered to be acid.

What is the scaling factor if the molar mass of
Step2247 [10]

Answer:

The scaling factor is 5.

Explanation:

Hello there!

In this case, since the scaling factor is defined as the ratio of the molar mass of the molecular formula (complete) to the empirical formula (simplified), it is possible to compute it for the empirical formula of CH2O whose molar mass is 30 g/mol (12+2+16) as shown below:

sf=150/30=5

Therefore, we can also infer that the molecular formula would be:

C_5H_1_0O_5

Best regards!
