Convert 0.9% glucose to g/100ml?

Biology

Answer:

If we consider a solution density of 1 g/ml, it is 0.9 g/100ml

Explanation:

A solution 0.9% glucose can be expressed as follows:

\frac{0.9 g glucose}{100 g solution} \\

If the density of the solution (at a given temperature) is 1 g/ml, the solution concentration can be calculated as follows:

\frac{0.9 g glucose}{100 g solution} . \frac{1 ml solution}{1 g glucose} = \frac{0.9 g glucose}{100 ml solution}

So, to calculate a solution concentration in g/ml from a %w/w concentration you have to only divide it into the solution density. Remember that solution density depends on the temperature.

Convert a 0.9% glucose solution to g/ 100 ml.

How many grams of glucose would you need to add to 1 liter of water to make a 0.9% glucose solution?  Use dimensional analysis.

If you had a 0.9% glucose solution how many mol/L do you have?  Calculate glucose’s molecular weight first and then use dimensional analysis to calculate your final answer.

If you had a 0.9% glucose solution how many osmoles/L do you have?  You have to take into account how many particles glucose dissociates into.

If you had a 0.9% NaCl solution how many osmoles/L do you have?  You have to take into account how many particles NaCl dissociates into.

4. What is meant by the fact that water is a "polar" molecule?
Ksju [112]

Hello!

A polar molecule is where one of the atoms in a molecule has a slight positive charge, and another has a slight negative charge, due to the unequal sharing of electrons.

Water is one of these molecules - the electrons spend more time around the oxygen atom in the center, and less around the hydrogens, so the hydrogen atoms have a slight positive charge, and the oxygen a slight negative.

Therefore, your answer is B, water has a slight negative and a slight positive charge at opposite poles.

Hope this helps!

tangare [24]

Answer: Human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed biologically, we humans are Hono Sapines, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.

Autotrophs that utilize light as their energy source are
k0ka [10]

The correct answer is - phototrophs.

Some of the autotrophs are able to convert the electromagnetic energy from the sunlight into chemical energy in the form of reduced carbon (C). The autotrophs that are able to perform this are called phototrophs. The green plants and the algae are the most prominent members of the phototroph autotrophs.

In essence, the autotrophs are producers, meaning that they are able to produce their own food. The phototrophs are the part of the autotrophs that are able to use the sunlight to produce small amounts of ATP as well as the energy carrier NADHP. By producing the ATP and the NADHP the phototrophs manage to produce glucose, or rather sugars, which are actually their food.
