Answer:

5.312286 * 10^{26} atoms are in 882 moles of Li.

Step-by-step explanation:

Use the conversion to get moles into atoms.

x atoms = 882 moles = 6.94 g Li      Since we are using atoms and moles, ignore the grams

x atoms = 882 mol * \frac{6.023*10^{23}atoms }{1 mol}  The moles cancel, so just multiply

x atoms = 5.312286 * 10^{26}

Answer: The number of times a yellow cube will be drawn is 390 times.

Step-by-step explanation: Like the last question with the blue cubes, set up a ratio.

Since it is still 240 times drawn and we need to figure out how many times a yellow cube will be drawn from 1200 times, the top number only changes.

78/240 = x/1200

Multiply 78 and 1200, which is 93,600.

Divide that by 93,600, which is 390.
