> 2,000 mL of a 5.0 × 10–5% (w/v) sucrose solution 

5.0 × 10–3 g/mL * 2000 mL * (1 mol / 342.30 g) = 0.0292 mol

<span>
> 2,000 mL of a 5.0 ppm sucrose solution</span>

5 grams / 1000000 mL * 2000 mL* (1 mol / 342.30 g) = 0.0000292 mol

 <span>
> 20 mL of a 5.0 M sucrose solution </span>

5.0 M * 0.020 L = 0.1 mol

 

 

Answer:

What is the specific activity (in Ci/g) if 1.65 mg of an isotope emits 1.56X10⁶α a particles per second?
marta [7]

The specific activity (in Ci/g) if 1.65 mg of an isotope emits 1.56X10⁶α a particles per second.

<h3>What is isotope?</h3>

Isotopes are two or more types of atoms with the same atomic number (number of protons in their nuclei) and periodic table position (and so belong to the same chemical element), but distinct nucleon numbers due to differing numbers of neutrons in their nuclei. While all isotopes of a given element have nearly identical chemical properties, their atomic weights and physical properties differ.

The term isotope is derived from the Greek roots isos and topos, which means that different isotopes of the same element occupy the same position on the periodic table. Margaret Todd, a Scottish doctor and writer, coined the phrase in 1913 as a recommendation to British chemist Frederick Soddy.

. Ana has two mixtures. Mixture 1: marble and salt. Mixture 2: Salt and pepper She predicts she can easily separate the ingredie
MariettaO [177]

Answer:

No

Explanation:

No, Ana's prediction of sorting out : mixture 1 'marble salt' with by her fingers, ie handpicking is not right.

Marble & salt particles mixture can't be sorted by handpicking. They can be seperated by the method of sieving rather, as marble particles being bigger stay in the sieve & salt particles being smaller (finer) pass through it.
