Answer:

Quartz is the hardest mineral of the minerals on the table.

Explanation:

Since a scratch was produced with Chalcopyrite, Pyrite and Orthoclase but not on Quartz, clearly Quartz was the hardest mineral of the minerals that were tested.  To prove this, we can search up the hardness of each mineral.  Quartz on the hardness scale is 7, Orthoclase on the scale is 6, Pyrite is 6 and Chalcopyrite is 4.  Quartz being the highest at 7 is the hardest of the minerals

The average 70 kg (150 lb) being has 5.5 L of blood (1.05 g/mL). How many 1 oz drinks of 20% alcohol by volume (40 proof) must b
AlekseyPX

Answer:

The total blood given is 5.5 liters

Thus, total alcohol needed for BAC (blood alcohol content) to exceed 0.1 gram per 100 ml will be 0.1/100 × 5500 = 5.5 grams alcohol.

1 oz = 28.3 grams

28.3 gram water = 28.3 ml

It has 20 percent alcohol by volume,

Therefore, alcohol in one drink will be:

20/100 × 28.3

= 5.66 ml

= 5.66 × 0.79 (density of ethanol)

= 4.47 gram

Thus, no of drinks will be 5.5 g / 4.47 g = 1.2

Hence, 1.2 drinks will make the BAC to exceed 0.1 g / 100 ml in the blood.
