How many moles of argon are equal to 3.01×1023 atoms

1 answer:

5 0

To convert from atoms of argon to moles of argon, you need to divide by Avogadro's constant.

3.01*10^23 atoms *(1 mole/6.022*10^23 atoms) = 0.500 moles Ar

0.500 moles of Argon is equal to 3.01*10^23 atoms of Argon.

A 44% wt/wt solution of H2SO4 has a density of 1.343g/ml. What mass of H2SO4 is 60ml of this solution?

horsena [70]

<u>Answer:</u> The mass of sulfuric acid present in 60 mL of solution is 34.1 grams

<u>Explanation:</u>

We are given:

44 % (m/m) solution of sulfuric acid. This means that 44 grams of sulfuric acid is present in 100 grams of solution.

To calculate volume of a substance, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

Density of solution = 1.343 g/mL

Mass of solution = 100 g

Putting values in above equation, we get:

$1.343g/mL=\frac{100g}{\text{Volume of solution}}\\\\\text{Volume of solution}=\frac{100g}{1.343g/mL}=77.46mL$

To calculate the mass of sulfuric acid present in 60 mL of solution, we use unitary method:

In 77.46 mL of solution, mass of sulfuric acid present is 44 g

So, in 60 mL of solution, mass of sulfuric acid present will be = $\frac{44g}{77.46mL}\times 60mL=34.1g$

Hence, the mass of sulfuric acid present in 60 mL of solution is 34.1 grams

Which of the following aspects of biotechnology is Not considered to be a moral or ethical issue?

a.research and testing on animals

b.cloning living material

c.reducing research cost

d.damaging the environment

Answer:

c.reducing research cost

Explanation:

Ethical issues arise when a particular course of action is at odds with the generally acceptable moral standard in the society.

Research and testing on animals is contested as an ethical issue by animal rights activists.

Cloning living material is prohibited among some sections of society and is also being contested as an ethical issue.

Damaging the environment the environment owing to biotechnology research is generally regarded as an ethical issue.

However, reducing research cost is highly acceptable in any research. It does not pose an ethical issue.
