The answer is; All of them

A molecule is a stable chemical unit (with neutral charge) of atoms chemically bonded together (these bonds can be covalent, metallic, ionic, and etcetera). The molecule can, therefore, be of an element (contain atoms of the same element – in this case, N2 and O2) or a compound (atoms of different elements- in this case, H2O and NaCl).

KiRa [710]

Answer:

14,938 tablets.

Explanation:

WE divide:

1.21 kg / 81 mg

1.21 kg = 1,210 g = 1.210,000 mg.

So it is 1,210,000 / 81

= 14,938 tablets.

If 100 ml of a 0.5 M HCI Solution is diluted with water to 1000ml, what is the new concetration?
Vesna [10]

Answer:

0.05\ \text{M HCl}

Explanation:

V_1 = Initial volume = 100 mL

V_2 = Final volume = 1000 mL

M_1 = Initial concentration = 0.5 M

M_2 = Final concentration

We have the relation

\dfrac{M_1}{M_2}=\dfrac{V_2}{V_1}\\\Rightarrow M_2=M_1\dfrac{V_1}{V_2}\\\Rightarrow M_2=0.5\times \dfrac{100}{1000}\\\Rightarrow M_2=0.05\ \text{M HCl}

The new concentration is 0.05\ \text{M HCl}.
