Well accounting google,


Chemists generally use the mole as the unit for the number of atoms or molecules of a material. One mole (abbreviated mol) is equal to 6.022×1023 molecular entities (Avogadro's number), and each element has a different molar mass depending on the weight of 6.022×1023 of its atoms (1 mole).

<u>Answer:</u> The number of atoms in given amount of carbon are 2.78\times 10^{24}

<u>Explanation:</u>

We are given:

Moles of carbon atom = 4.61 moles

According to mole concept:

1 mole of a n element contains 6.022\times 10^{23} number of atoms

So, 4.61 moles of carbon will contain (4.61\times 6.022\times 10^{23})=2.78\times 10^{24} number of atoms.

Hence, the number of atoms in given amount of carbon are 2.78\times 10^{24}

if a 500.0-g block of metal absorbs 5,016J of heat when its temperature changes from 20.00 Celcius, what is the specific heat?
ZanzabumX [31]
Correction: The temperature change is from 20 °C to 30 °C.

Answer:
               Cp  =  1.0032 J.g⁻¹.°C⁻¹

Solution:

The equation used for this problem is as follow,

                                                  Q  =  m Cp ΔT   ----- (1)

Where;
            Q  =  Heat  =  5016 J

            m  =  mass  =  500 g

            Cp  =  Specific Heat Capacity  =  ??

            ΔT  =  Change in Temperature  =  30 °C  -  20 °C  =  10 °C

Solving eq. 1 for Cp,

                                 Cp  =  Q / m ΔT

Putting values,
                                 Cp  =  5016 J / (500 g × 10 °C)

                                 Cp  =  1.0032 J.g⁻¹.°C⁻¹

What is the h concentration in a solution with a ph of 1.25
lyudmila [28]

Answer:

0.056 M

Explanation:

To calculate the concentration of h we must use the following formula:

10^-pH

So lets plug in our pH:

10⁻¹.²⁵

When we plug this into our calculator our answer is

0.056 M

Calculate the gravitational force of attraction between a 26kg boy and his 5.1kg dog when they are separated by 0.19m
Pavel [41]

Answer:

Gravitational force of attraction G(f) = 2.44 x 10⁻⁷ (approx.)

Explanation:

Given:

Mass M1 = 26 kg

Mass M2 = 5.1 kg

Distance r = 0.19 m

Find:

Gravitational force of attraction G(f)

Computation:

Gravitational force of attraction G(f) = G(m1)(m2)/r²

Gravitational force of attraction G(f) = [6.67 x 10⁻¹¹](26)(5.1)/(0.19)²

Gravitational force of attraction G(f) = 8.84 x 10⁻⁹ / 0.0361

Gravitational force of attraction G(f) = 2.44 x 10⁻⁷ (approx.)
