To find the experimental value I believe we add up all the temperatures found by each trial and divide by the number of trials

When added up and divided up this is 50.7 C

Then we continue with accepted value minus experimental value over accepted

53.0 - 50.7 / 53.0 x 100

What is the mass of 2.9 moles of calcium? Show all work!
4vir4ik [10]

Answer:

the mass of 2.9 moles of calcium is 116 g

Explanation:

The computation of the mass of 2.9 moles of calcium is shown below

As we know that

Mole = mass ÷  molar mass

where,

Moles be 2.9

And, we know that the molar mass of calcium be 40g/mol

Now put the values to the above formula

2.9 = Mass ÷ 40

So, the mass would be

= 40 × 2.9

=   116 g

Hence, the mass of 2.9 moles of calcium is 116 g

A volume of a fixed gas is doubled and the temperature is doubled. What happens to the pressure of the gas?
Montano1993 [528]
We first assume that this gas is an ideal gas where it follows the ideal gas equation. The said equation is expressed as: PV = nRT. From this equation, we can predict the changes in the pressure, volume and temperature. If the volume and the temperature of this gas is doubled, then the pressure still stays the same.

lorasvet [3.4K]

Answer:

B

Explanation:

Molarity = 0.010M

Volume = 2.5L

Applying mole-concept,

0.010mole = 1L

X mole = 2.5L

X = (0.010 × 2.5) / 1

X = 0.025moles

0.025moles is present in 2.5L of NaOH solution.

Molar mass of NaOH = (23 + 16 + 1) = 40g/mol

Number of moles = mass / molar mass

Mass = number of moles × molar mass

Mass = 0.025 × 40

Mass = 1g

1g is present in 2.5L of NaOH solution
