How many grams are thee in 2.3times 10to the 23 power
What units are you measuring with 2.3 * 10^23? Are they pounds, ounces, kilgromas or something else? Without this information, it is impossible to answer your question.
Please repost with the needed information, so we can help you. I hope this helps a little. Thanks for asking.
2.3 x 1023 probably is the number of molecules. If that is true, then
2.3 x 1023/6.2 x 1023 = ?? mols
?? mols x molar mass = grams.
You didn't provide the element or compound; therefore, we don't know the molar mass. I hope this helps.
