Ideal gas law PV = nRT or PM = dRt ( M is molecular mass of gas ) and d is gas density
where m/ M ( m is mass of gas sample )
m = dRT / P ( 2.78 g/L ) ( 0.082 L atm/ K mole )( 310K ) / 1.2 atm =
58.9 g/mol
gas must be butane ( C4H10) has molecular mass = 58.9 g/mol
Answer:
Nickel
Explanation:
To find what metal it is, first find the density
Density formula: mass ÷ volume
so.. 26.7 ÷ 3 = 8.9 g/cm^3
Nickel has a density of 8.9 g/cm^3 so nickel is the metal that is present in the ring
<span>The answer is industrialists. Together with entrepreneurs preferred a comparatively open and flexible immigration policy – one which would safeguard a stable source of workers. Encompassed within this group were the chief steamship and railway businesses which seen immigrants as possible laborers and also vital passengers on their appearances and the basis of future traffic in terms of things and materials.</span>
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
