Answer:

The most common example is the molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal to 1.00 atm.If an ideal gas at a constant temperature is initially at a pressure of 3.8 atm and is then allowed to expand to a volume of 5.6 L and a pressure of 2.1 - 18914… ... of 5.6 L and a pressure of 2.1 atm, what is the initial volume of the gas? ... An ideal gas is at a pressure of 1.4 atm and has a volume of 3 L.

Silver chloride, often used in silver plating, contains 75.27%Ag. Calculate the mass of silver chloride required to plate 195 mg
kenny6666 [7]

Answer:

259 mg is the mass of silver chloride required to plate 195 mg of pure silver.

Explanation:

Silver chloride contains 75.27 percent silver. It can be concluded that:-

For every 100 mg of silver chloride, 75.27 mg of silver we can get.

So, to produce 195 mg of silver, the amount of silver chloride required can be calculated as:-

Mass=\frac{100\times 195}{75.27}\ mg=259\ mg

<u>259 mg is the mass of silver chloride required to plate 195 mg of pure silver.</u>

What is the energy of a photon of green light whose frequency is 6.85 X 1014/seC?
Anvisha [2.4K]

Frequency of photon = is 6.85 X 10¹⁴ sec⁻¹

Energy of photon , E = hv

where h is Planck's constant, v is the frequency of photon

E = 6.63 × 10⁻³⁴ J.s x 6.85 X 10¹⁴ s⁻¹

E = 4.54 x 10⁻¹⁹ J

Therefore, the energy of a photon of green light is 4.54 x 10⁻¹⁹ J.
