kolbaska11 [484]
1. 5 ethyl, 2 methyl octane
2. 1 ethyl, 2 methyl cyclopentane
3. 3,3,5,5- tetrafluoro heptane

keep in mind that between 4-7, there could be #1 in front of the main name. for example with #4: 3,4-dimethyl-1- hexene. this honestly depends on the professor how he/she likes it. It is not necessary because if the number is not specified, it is assumed is #1

One cup of milk contains 318 mg of calcium. A student drinks 0.318 L of milk in one day. How many mg of calcium does the student
loris [4]

Answer:

426 mg = 4.26 x 10² mg

Explanation:

1 cup = 237.6 mL x 1 L/1000 mL = 0.2376 L

We divide the liters of milk the student drinks into the volume in liters of a cup to calculate the number of cups the student drinks per day:

number of cups per day = 0.318 L/0.2376 L = 1.34 cup

Now, we multiply the number of cups by the amount of calcium that a cup of milk has:

amount of calcium = 1.34 cup x 318 mg = 426 mg = 4.26 x 10² mg

Therefore, the student gets 426 mg (or 4.26 x 10² mg) of calcium in one day.
