Determine the density of a substance with a volume of 3333 ML and a mass of 255g​.

Chemistry
1 answer:
alex41 [277]3 years ago

Answer:

The answer is

<h2>0.077 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

<h3>density =  \frac{mass}{volume}</h3>

From the question

mass of substance = 255 g

volume = 3333 mL

The density of the substance is

density =  \frac{255}{3333}  \\  =  \frac{85}{1111}  \\  = 0.07650765...

We have the final answer as

<h3>0.077 g/mL</h3>

Hope this helps you

Read the given equation. 2Na + 2H2O → 2NaOH + H2
Crank

Answer:

B) 12.9 grams.

Explanation:

How many moles of molecules in that 6.30 L of H₂?

The volume of one mole of an ideal gas at STP (0 °C, 1 atm) is 22.4 liters.

(The volume of that one mole of gas at STP will be 22.7 liters if STP is defined as 0 °C and 10⁵ Pa).

\displaystyle n(\text{H}_2) = \frac{6.30\;\text{L}}{22.4\;\text{L}\cdot\text{mol}^{-1}} = 0.28125\;\text{mol}.

How many moles of Na will be needed?

The coefficient in front of Na in the equation is twice the coefficient in front of H₂. It takes two moles of Na to produce one mole of H₂.

n(\text{Na}) = 2\;n(\text{H}_2) = 2\times 0.28125= 0.5625\;\text{mol}.

What's the mass of that many Na atoms?

Refer to a modern periodic table. The molar mass of ₁₁Na is 22.990. The mass of one mole of Na atoms is 22.990 gram. The mass of 0.5625 moles of Na atoms will be

m = n\cdot M = 0.5625 \times 22.990 = 12.9\;\text{g}.

(2 sig. fig. as in the volume of the H₂ gas.)

What are radioactive tracers used for
Reptile [31]

Answer:

Radioactive tracers are widely used to diagnose industrial reactors, for instance by measuring the flow rate of liquids, gases and solids.

Explanation:

Radioactive tracers are widely used to diagnose industrial reactors, for instance by measuring the flow rate of liquids, gases and solids. A radioactive tracer is a chemical compound in which one or more atoms have been replaced by a radioisotope.

Boron has an average atomic mass of 10.81. One isotope of boron has a mass of 10.012938 and a relative abundance of 19.80 percen
Georgia [21]
The average atomic mass is calculated by the expression:

Average atomic mass = Σzₓ(Aₓ)

where zₓ is the relative abundance of an isotope and Aₓ is the atomic mass of the isotope. 

We calculate the mass of the isotope as follows:

10.81 = .1980 (10.012938) + .8020 (x)
x = 11.00 -----------> mass of the isotope
