Neporo4naja [7]3 years ago
8 0
According to picture below, answer is d.c4h2n2o4 and c2hno2.
Molecular formula is chemical formula that shows the total number and kinds of atoms in a molecule, but not their structural arrangement (in this case C₄H₂N₂O₄). Molecular formula shows that compound has four carbon, two hydrogen, two nitrogen and four oxygen atoms.
Empirical formula gives the proportions of the elements present in a compund but not the actual numbers or arrangement of atoms. C : H : N : O = 2 : 1 : 1 :2.

Intravenous, or IV, solutions used in medicine must exert the same osmotic pressure as blood to prevent a net flow of water into
Novosadov [1.4K]

Answer:

\boxed{\text{7.5 bar}}

Explanation:

1. Find the molar concentration

Assume that we have 100 mL solution.

Mass of NaCl = 0.90 g

\text{Moles of NaCl} = \text{0.90 g} \times \dfrac{\text{1 mol}}{\text{58.44 g}} = 0.0154 \text{ mol}\\\\c = \dfrac{\text{Moles of NaCl}}{\text{Litres of solution}} = \dfrac{0.0154 \text{ mol}}{\text{0.100 L}} = \text{0.154 mol/L}

2. Find the osmotic pressure

The formula for osmotic pressure (Π) is

Π = icRT

T = (37 + 273.15) K = 310.15 K

\Pi = 1.88 \times \text{0.154 mol}\cdot \text{L}^{-1} \times \text{0.083 14 bar}\cdot\text{L}\cdot\text{K}^{-1}\text{mol}^{-1} \times \text{310.15 K} = \text{7.5 bar}\\\\\text{The osmotic pressure of blood at body temperature is }\boxed{\textbf{7.5 bar}}

How much of a 400g sample remains after 4 years if a radioactive isotope has a half-life of 2 years?
timama [110]

Answer:

100 g

Explanation:

From the question given above, the following data were obtained:

Original amount (N₀) = 400 g

Time (t) = 4 years

Half-life (t½) = 2 years

Amount remaining (N) =?

Next, we shall determine the number of half-lives that has elapse. This can be obtained as follow:

Time (t) = 4 years

Half-life (t½) = 2 years

Number of half-lives (n) =?

n = t / t½

n = 4 / 2

n = 2

Thus, 2 half-lives has elapsed.

Finally, we shall determine the amount remaining of the radioactive isotope. This can be obtained as follow:

Original amount (N₀) = 400 g

Number of half-lives (n) = 2

Amount remaining (N) =?

N = 1/2ⁿ × N₀

N = 1/2² × 400

N = 1/4 × 400

N = 0.25 × 400

N = 100 g

Thus, the amount of the radioactive isotope remaing is the 100 g.
