Imagine you need to explain to a friend how to convert a value on a food label to one that is measured in grams. Assume the package of food has a mass of 1.0 pounds. write an explanation for how to use dimensional analysis to convert this value to one expressed in grams.
Answers
Answer:
453.592 grams
Explanation:
Given
Mass = 1 lb
Required.
Convert to grams using dimensional analysis
Represent 1 lb with x g
In unit conversion, we have that.
1 lb = 453.592 g
So:
Getting the equivalent of lb in g, we have:
x g = 1 lb * (453.592 g/ 1 lb)
x g = 1 * 453.592 g
x g = 453.592 grams
Hence:
The equivalent of 1 lb in grams is 453.592 grams
Does Kumiho the legendary exist??
Answers
Answer: Deriving from ancient Chinese myths and folklores, a fox that lives a thousand years turns into a kumiho, like its Japanese and Chinese counterparts. It can freely transform, among other things, into a beautiful woman often set out to seduce boys, and eat their liver or heart (depending on the legend).
Hoped that helped!
Answer:
No
Explanation:
The Kumiho is similar to other fox creatures, such as the Japanese kitsune and Chinese Huli jing. Even though they have similar magical abilities and longevity, Kumiho is more malevolent than other fox spirits. Of these long-lived legendary creatures, the Kumiho is the only fox that kills and eats humans. Kumiho is just a myth itś not real and no one has seen this fox so "it" does not exist.

does water in a glass have mass
Answers
Answer:
A glass of water, or 200 grams of water, therefore contains 6.6855 × 1024 water molecules. The total mass of the hydrosphere is about 1.4 × 1024 grams, and thus the total hydrosphere contains about 7 × 1021 glasses of water (with 200 grams of water in each).
Explanation:
Answer:
Just like solids, liquids also have their own characteristic density. ... Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter. The density of a substance is the same regardless of the size of the sample.
Matter is generally defined as any thing that has mass and occupies spaces. Matter is generally divided into three categories ; solid, liquid and gas. Water is a liquid, water has does have molecules, thus has a mass, and is suspended in an area such as water in glass.
SO YES WATER IN A GLASS HAS MASS :)Hope this helps ~OwO~

A student places 1.38g of unknown metal at 99.6C into 60.50g of water at 22.1C. The entire system reaches a uniform temperature at 31.6C. Calculate the specific heat of the metal
Answers
Explanation:
Heat energy lost by metal = Heat energy gained by water.
(0.00138kg) * c * (99.6-31.6) = (0.006050kg) * 4.148 * (31.6-22.1)
