The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is18.02 grams. This is stated: the molar mass of water is 18.02 g/mol. Notice that the molar mass and the formu...

To determine the formula of the unknown gas weighing 1.25 g per liter at STP (Standard Temperature and Pressure), we can follow these steps:1. Understanding STP: At STP, 1 mole of any gas occupies 22.4 liters. This means that i
[186] reported that GWP per mole is two times lower for sodium hydroxide than for sodium silicate, but as Habert and Ouellet-Plamondon [191] calculated the CO2-eq per kg of the dry component (i.e. without the water) with the updated data, the difference between sodium hydroxide and ...
