# What are STP and give its value?

Key Takeaways: STP or Standard Temperature and Pressure One common definition of STP is a temperature of 273 K (0° Celsius or 32° Fahrenheit) and the standard pressure of 1 atm. Under these conditions, one mole of a gas occupies 22.4 L.

## What is the STP in chemistry?

## How many molecules does STP have?

At STP 1 mole of an ideal gas = 22.4 liters. Assuming that water vapor behaves as an ideal gas, then… 0.08929 moles H2O x 6.02×1023 molecules/mol = 5.4×1022 molecules = 5×1022 molecules (1 sig. fig.)

## What is the value of R in SI system?

R is known as the universal gas constant =8.3145J/mol. K. The value of the gas constant ′R′ depends on the units used for pressure, volume and temperature. When we use the gas constant R = 8.31 J/K.

## What is the value of R in ATM L mol K?

The Gas Constant (R) If you use the first value of R, which is 0.082057 L atm mol-1K-1, your unit for pressure must be atm, for volume must be liter, for temperature must be Kelvin.

## What are the units for gas constant?

Solution : For specific gas constant unit : Joule`//`kelvin Demensional formula: `r = (PV)/T = ML^(2)T^(-2)L^(-1)`.

## What does the R mean in R value?

R-Value is the rating system used to grade insulation products or a material’s insulating properties. The “R” stands for “resistance” and refers to the resistance a material has to heat flow, or temperature conduction. When a product or home has a high R-Value, this means it is well insulated.

## What is Pearson R used for?

The Pearson correlation coefficient (r) is the most common way of measuring a linear correlation. It is a number between –1 and 1 that measures the strength and direction of the relationship between two variables. When one variable changes, the other variable changes in the same direction.

## How do you find R value in Excel?
