How many grams are there in 1.50x10^22 molecules of N2H6

m = 0.85 g N2H6

Explanation: To find the mass of N2H6 we need to convert molecules of N2H6 to moles and convert it to mass using the molar mass of N2H6.

1.50x10²² molecules N2H6 x 1 mole N2H6 / 6.022x10²³ molecules N2H6

= 0.025 mole N2H6 convert to mass.

0.025 mole N2H6 x 34 g N2H6 / 1 mole N2H6

= 0.85 g N2H6

la respuesta es si te gusta hacer lo que siempre haces cuando nunca ves a alguien en el espejo porque sabes que no siempre están ahí.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
