Analyzing text confusion

I’m considering the phrase “какой масса?” and wondering if it should be “какая масса?” instead. At one position, I see "20 Н" with some distortion on the left edge. There's also an "Н" that might clarify things. So I suspect I'm dealing with two forces: 11 N and 20 N, leading to mass calculations using the equation \(F = mg\). I think the answers could potentially be 1.1 kg and 2 kg, though that second force looks like it could actually be 12 N. I'll need to check that visual detail again.Interpreting displayed text

I'm looking at the text around y 330 and wondering if it says "11 Н." I see a "1" at x 32, another "1" at x 83, and then "Н" at x 160. If that's 11 N, then the mass would be 1.1 kg. The bottom might say "30 Н" or "20 Н."

I also notice some strokes that might form the word "полон," and I’m considering if the task is about chemistry. I wonder if "молекулярная масса" relates to the numbers I'm seeing, like "Na." There’s a lot to dissect here!Considering chemical elements

I’m thinking this might relate to the periodic table, with “11 Na” and “20 Ca,” both asking about their charges. The question "Какой заряд ядра?" suggests it’s about atomic properties. Wait, there's more! The visible text around y 180 could be asking about "молекулярная масса?" which fits perfectly in a chemistry context. I feel like I'm piecing together clues to understand the larger task here! Let’s see where this leads!
