A 10.0 mL syringe contains 0.10 g of nitrogen gas at 0.0 degrees Celsius. What is the pressure inside the syringe?
Ad libitum [116K]
Since the sample inside the syringe is a gas, we assume that it is an ideal gas that is we use the expression PV = nRT. We can easily calculate the pressure as follows:

n = m /MM = 0.10 / 28 = 0.0036 mol

P = nRT / V = 0.0036(0.08206)(273.15) / 0.010
P = 8 atm

How many moles are in 325mL of 1.25M (NH4)2SO4
mote1985 [20]

Answer:

n_{solute}=0.406mol(NH_4)_2SO_4

Explanation:

Hello,

In this case, since the molarity is defined as the ratio of the moles of the solute to the volume of the solution in liters:

M=\frac{n_{solute}}{V_{solution}}

For the given volume and molarity, we solve for the moles of ammonium sulfate (solute) as shown below:

n_{solute}=M*V_{solution}=1.25\frac{mol}{L}*325mL*\frac{1L}{1000mL}  \\\\n_{solute}=0.406mol(NH_4)_2SO_4

Best regards.

How many hydrogen atoms are present in 5.00 mg of aspartame?
RideAnS [48]

Aspartamate is methyl ester of aspartic acid. It is used as an artificial sweetener in foods and beverages. The molecular formula of aspartamate is: C₁₄H₁₈N₂O₅. Molecular mass of aspartamate is 294.3 g/mol.

294.3 g of aspartamate contains 1 mol of aspartamate= 6.023 X 10²³ number of aspartamate molecules. So, 5 mg of aspartamate contains (5 X 6.023 X 10²³)/ (294.3 X 1000) = 1.023 X 10¹⁹ number of aspartamate molecules. Each molecule of aspartamate has 18 H-atoms, so, 5 mg i.e, 1.023 X 10¹⁹ number of aspartamate molecules contain 18 X 1.023 X 10¹⁹= 1.84 X 10²⁰ number of hydrogen atoms.

vovikov84 [41]

Answer:

1. One atom splits

2. large

3. neutrons

Explanation:

In the process of nuclear fission,1__one atom splits___.Fission only happens to very 2(__large___) atoms.The Fission process usually also produces several free 3(__neutrons___).

Nuclear fission is a radioactive decay process in which heavy and unstable radioactive nucleus decays into lighter ones with the release of energy and free neutrons.

Fission differs from fusion in that in nuclear fusion, two light atoms comes together to form a large one. This process releases a very great amount of energy.
